Detailed description of the invention
It should be noted that, when not conflicting, the embodiment in the utility model and the feature in embodiment can combine mutually.
Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
Embodiment one
The present embodiment relates to a kind of automobile front subframe assembly structure, as shown in fig. 1, it comprises subframe body 1, be connected to left longeron 2 and the right vertical beam 3 at subframe body 1 two ends, and the front cross rail 4 between the other end being connected at left longeron 2 and right vertical beam 3 relative to subframe body 1, between left longeron 2 and right vertical beam 3, edge is near the direction of front cross rail 4 in the splayed structure extended out, and left longeron 2 and right vertical beam 3 is equipped with the generation crumple distortion when left longeron 2 and right vertical beam 3 bear external impact, to carry out the crumple portion of snubber to external impact.
At front cross rail 4 place, can front-suspension bracket be set in the present embodiment, for the connection of subframe and front-suspension.And as shown in Figure 2, the upper surface of subframe body 1 is also connected with near its two ends place the base member 11 making to be connected between subframe body 1 with not shown vehicle body respectively, base member 11 is provided with and makes between base member 11 and vehicle body, to carry out bolted fixed orifice 12, be also provided with the breach 13 be connected with fixed orifice 12 inside in the edge, side of base member 11.
In the present embodiment, the shape that extends out of left longeron 2 and right vertical beam 3 is arranged so that the entire length of front cross rail 4 is elongated, and the increase of the spacing of left longeron 2 and right vertical beam 3 ensure that the gap between both and automobile power assembly meets the demands.The concrete structure of left longeron 2 is as shown in Fig. 3 to Fig. 5, and left longeron 2 is enclose by upper plate 8 and lower plate 9 cavity body structure be configured to, and adopts cavity body structure can ensure the structural strength of left longeron 2 self, is connected to realize between front cross rail 4 with subframe body 1 reliable.And be ensure that the gap between automobile power assembly and transmission assembly is in more than safety value in actual use, side also near right vertical beam 3 on left longeron 2 in the present embodiment is provided with a relief portion 7, relief portion 7 is the concave inward structure arranged along the length direction of left longeron 2, and its concrete structure size can be selected according to the structural volume of dynamic assembly.
In the present embodiment, the structure of right vertical beam 3 is roughly the same with left longeron 2, and it is also cavity body structure, just on right vertical beam 3, does not arrange avoiding structure.And be connected for ease of left longeron 2 and the dismounting between right vertical beam 3 with subframe body 1, left longeron 2 and being also between right vertical beam 3 with subframe body 1 is connected via bolt, simultaneously in order to make left longeron 2 and be connected between right vertical beam 3 with subframe body 1 more firm, in the present embodiment also as shown in Figure 6, at left longeron 2(right vertical beam 3) bolt junction be provided with and be installed between upper plate 8 and lower plate 9 and with the mounting sleeve 14 of bolt connecting hole.Except left longeron 2 and with bolts between right vertical beam 3 and subframe body 1 in certain the present embodiment, and arrange outside mounting sleeve 14 in left longeron 2 and right vertical beam 3, left longeron 2 and the connection between right vertical beam 3 and front cross rail 4 also can be with bolts form, and also at left longeron 2 and right vertical beam 3, mounting sleeve 14 is set with the junction of front cross rail 4.
And the crumple portion on left longeron 2 and right vertical beam 3 of being arranged in the present embodiment can left longeron 2 in Fig. 3 be described for example, now crumple portion is located at left longeron 2 is positioned at the structural sections that the cross sectional dimensions in the middle part of left longeron 2 reduces, when left longeron 2 is subject to external impact, the intensity of the structural sections reduced because of this cross sectional dimensions is lower, thus left longeron 2 can be made in bending, thus realize the snubber of impact energy herein.Certainly except the structural sections of above-mentioned reduced cross-sectional, crumple portion in the present embodiment also can be the structural sections bending in serpentine be located on left longeron 2 and right vertical beam 3, or for being located at the structural sections bending in serpentine on left longeron 2 and right vertical beam 3, and the cross sectional dimensions of structural sections that this serpentine bends reduces.In addition except aforementioned structure form, crumple portion also can be located on left longeron 2 and right vertical beam 3 with the structural sections of " V " connected in star, and this structural sections is gradually little along its cross sectional dimensions of direction near " V " connected in star.
Left front lower swing arm assembly 5 and right front lower swing arm assembly 6 is connected in the below at subframe body 1 two ends in the present embodiment, be connected with the dismounting between subframe body 1 with right front lower swing arm assembly 6 for ease of left front lower swing arm assembly 5, to improve the convenience of later period maintenance, left front lower swing arm assembly 5 and right front lower swing arm assembly 6 be also all designed between subframe body 1 be connected via bolt, simultaneously in order to promote left front lower swing arm assembly 5 and the switching performance between right front lower swing arm assembly 6 and subframe body 1, also lining 10 is provided with at left front lower swing arm assembly 5 and right front lower swing arm assembly 6 with the junction of subframe body 1 in the present embodiment, lining 10 can adopt various suitable that market is sold, for left front lower swing arm assembly 5, the structure that arranges of lining 10 can be as shown in Figure 7.
What this automobile front subframe assembly structure utilized left longeron 2 and right vertical beam 3 extends out shape vibrational power flow, by the change moved towards both, ensure that the gap width between subframe and automobile power assembly.And when automobile collides, realize the snubber to collision energy by the crumple portion design on left longeron 2 and right vertical beam 3 again.If when collision is simultaneously comparatively serious, except left longeron 2 and the snubber of right vertical beam 3 pairs of collision energies, because fixed orifice 12 place on base member 11 is provided with breach 13, now larger collision impact also can make base member 11 in breach 13, have the trend of tearing, thus further snubber can be carried out to collision energy, reduce the transmission of collision energy to automobile passenger compartment direction.Certainly for ensureing that base member 11 place can tear, the structural strength being located at the place of crumple portion on left longeron 2 and right vertical beam 3 can not be too weak, and it can be selected according to material property when specific design.
Embodiment two
The present embodiment relates to a kind of vehicle body, this vehicle body is equiped with the automobile front subframe assembly structure as described in embodiment one, via this automobile front subframe assembly structure, shock sucking structure can be increased on the one hand on the basis of motor tire, suspension, swing arm, improve the travelling comfort of vehicle, also the constructional feature of this automobile front subframe assembly structure can be utilized on the other hand to improve the structural stability of automobile, and promote the overall collision performance of automobile.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
